- As you stand by the side of the road, a acr approaches you at a constant speed, sounding its horn, and you hear a frequency of 80.0 Hz. After the car goes by, you hear a frequency of 60.0 Hz. What is the speed of the car? The speed of sound in the air is 343 m/s. The answer shoudl be 49m/s, I am more confused on how to solve algebraically. I attached a photo of how far I made it lol.3 and 44-
- Two waves of the same frequency have amplitudes 0.841 and 1.64. They interfere at a point where their phase difference is 47.0°. What is the resultant amplitude? Number Units eTextbook and MediaQuestion-10.6 A train is travelling at a speed of 20.3 m/s towards a station. The train whistle sounds with a frequency of 483.9 Hz. What is the frequency of the whistle as heard by someone on the station platform? Use the speed of sound in air of 340 m/s.Two loudspeakers S1 and S2, 6.0m apart, emit the same single-frequency tone in phase at the speakers. A listener L directly in front of speaker S1 notices that the intensity is a maximum when she is 8.0 m from that speaker (see figure). What is the lowest frequency of the emitted tone? The speed of sound in air is 340 m/s. 6 m S2
